Physical Sciences: Krypton-85 in the Troposphere

Nature volume 233, pages 614–615 (1971)Cite this article

Abstract

KRYPTON-85 produced by fission in nuclear reactors is at present the most abundant man-made radioisotope in the troposphere. Its activity in air was 33 d.p.m. m−3 air by the end of 1969 and it continues to increase. In this communication we report recent measurements of the 85Kr activity in samples from air liquefaction plants at Oberhausen and Duisburg in West Germany.
